BOILER-CLEANING COMPOUND.

SPECIFICATION forming part of Letters Patent No. 728,627, dated May 19, 1903.

' Application filed April 1, 1902. Serial No- 101,009- (No specimensl To all whom, it Inay concern:

Be it known that we, JOSEPH D. SCoTT, a resident of South Shields, and HENRY POLK SCOTT, a resident of Poplar, London, E. 0., England, subjects of the King of Great Britain, have invented new and useful Improvements in Boiler Cleaning Compounds, of which the following is a full, clear, and exact description.

This invention relates to a means for preventing and removing incrustations or like deposits from steam-boilers.

The object is to provide a compound which will be inexpensive and efficient and will not involve the risk of corroding and otherwise injuring the plates, tubes, or mountings of the boiler.

gallons of water by heat or otherwise.

It is also an object of the invention to provide a compound which may be stored in compact form and readily put in condition for use when desired, thus making it especially adaptable to marine purposes.

To this end the invention consists of a mixture of catechu and a viscous substance,such as molasses. Preferably this is prepared in the form of a semisolid compound, so that it may be compactly stored and subsequently dissolved in a sufficient quantity of water to place it in condition for use. To produce this semisolid compound, we proceed in the following ,manner: About twenty eight pounds of catechu are dissolved in about three Fiftysix pounds of molasses is then added and the compound is thoroughly mixed. This done,

the compound is complete in semisolid form and is ready for shipment.

To apply the compound to the boilers, it is only necessary to make a solution in water of the semisolid compound described above, and this solution should be pumped or otherwise introduced into the boiler, either alone or mixed with the feed-water. When thus employed, it will both dissolve the existing incrustation and prevent the formation of further incrustation.

We do not desire to limit ourselves to the nature of the viscous substance which is combined with the catechu, but it is preferably molasses or some immediate equivalent, such as sugar or sugar and molasses mixed.

Having thus described our invention, we claim as new and desire to secure by Letters Patent A boiler-cleaning compound, consisting of a mixture of catechu and molasses in essentially the proportions stated.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
